IMPROVEMENT IN CARRIAGE-CLIP.

TO ALL WHOM IT MAY CONCERN: 1

Be it known that I, G. B SALMON, of St. Paul, in the county of Ramsey and State of Minnesota, have invented a new. and improved Carriage-Clip, and I do hereby declare that the, following is a full, clear, and exact description thereof, which will enable others skilled in'the art to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which v Figure 1 is a side view of the rear end of a thill with myimproved clip attached, a part being'brok-en away to show the construction, showing in red lines the position of thc'parts when the forward end of the thill rests upon the ground, and in red dotted lines the positionof the parts when the thill is being detached.

Figure 2 is a top view of the same, a part being broken away to show the copstruction.

Similar letters of reference indicate like parts.

The object of-my invention is to frirnishan easy means by which the thills or pole may be att-ached to or detached from-the carriage in changing the one for the other, or to economize room in the carriage-house; and it consists, first, in connecting the thi'lls to the carriage b'y means of a hook formed upon the under side of the thill-' iron and near its front end, where itis attached to the thill; second, in thecombination of the thill-irons with the carriage-clip, when said parts are constructed substantially its-hereinafter described; third, in-the combination of the rubber plate with the thill-irons, andwith the clip, as hereinafter more fully described, and to prevent the end of the thill-iron and clipB from wearing away by the great friction caused by two substances of the same material working against each other.

A is the axle of the carriage 3 B is the clip, which isattached to the axle A by means of the bar 0 and nuts D, in the ordinary manner. Upon the forward side of the clip Bis formed a projection, 6 having projecting arms, 6 the ends of which are connected by a belt or pinion, Zr. The forward side of the projection '6 between the arms b is made circular or concave, as shown in fig. 1. The middle parts of the arms 11 may be cut away, if desired, to make them lighters E E are the thill-irons, which are attached to the thills 1* in the ordinary manner. Nearly upon the front end of the thill-irons E is, formed a hook, 6 which hooks around the belt or pinion Z1 as shown in the drawings. The rear end or head of: the thill-iro'n E is made circular orconvexto correspond with the concave face of the clip 13; and the hook and clip are so formed that they can only be detached by raising the thills into a vertical position, as shown in dotted lines in fig. 1. When in this position they can be readily lifted up, and detached from the carriage. c are shoulders, formed upon. the sides of the thill-irons E, which, when the thills have been raised into a vertical position by coming in contact with the arms 6 prevent the thill-irons from passing down between the said arms 6 any farther than just far enough to detach the hook e from the bolt 6 G is a rubber plate, placed between the convex head ofthe thill-i'ron E,

and the concave face of the projection Zr, as shown in fig. 1. The upper and lower ends of the plate G extenda little above and below the upper and lower sides of the projection I), and it has ears formed upon its side edges which rest upon the upper and lower edges of the arms [1 and which prevent the said plate from Working out of place. If desired, the projecting upper and lower ends of the plate Gr may be strengthened by having metallic strips riveted to them, as shown in figs. 1 and 2. Thus, it will be seen that the rear'end of the thilliron E being convex, and the front'end of the clip B being concave, having for its centre. or fulcrum the bolt 6 around which the hook e catches, the endof the thill-iron E is made to move in a radius of equal distance from its centre 6 and which will make half a circle in these relative positions, the rear end of the thill working in the front end of the clip, thus keeping at all times when in'use the hook 2 around bolt 6 nor is it possible for it to come off while'drawing the carriage. The plateG is not used as a spring, but is inserted, being of a difl'erent and softer material than the thill-iron and the clip B, to prevent the great friction caused by two surfaces of the same kind working against each other. It will lie-seen that-while the radius and centre are preserved no spring is needed, and the clip cannot rattle.

Having thus described myinvention, I claim as new, and desire to secure by Letters Patent- The combination of the thill-iron E, clip B, and rubber plate G, and boltb", the whole constructed and operating substantially as described and for the purposes set forth.

The above specification of my invention signed by me this 27th day of July, 1866.
